This card actually plugs into the CPU socket of the A500/A2000. The
68000 which has been removed from the CPU socket is placed onto the
ATonce board. This card is known to have some problems with A500
motherboard revisions older than 6A and requires some special
configuring. This card has printer and serial support. The original
package contained a 64pin IC socket for interfacing between the CPU
socket and the card, 2 floppy disks which contained a system disk and a
dos utility with manual.
